z = \frac{35}{2}

Decimal Notation

z = 17.5

Solution steps

\frac{7}{z} = \frac{10}{25}

175 = z \cdot 10

Switch sides

z \cdot 10 = 175

Divide both sides by

10

z = \frac{35}{2}

Verify Solutions

Find undefined (singularity) points:

z = 0

Combine undefined points with solutions:

z = \frac{35}{2}

\frac{8 x ^{2} + 3 x - 2}{2 x - 1} = 4 x

\frac{15}{8} = \frac{6}{x}

\frac{- 9}{- 3 x + 8} + 3 = 4
